Sock Bun.

Gently comb your hair back and away from your face
Depending on your bun preference, whether it be high or low, create a tight ponytail.
Take a clean sock and cut the tip of it off, where your toes would normally fit in
Roll the sock up into a scrunchie
Slide the sock scrunchie onto your ponytail so that the entire ponytail is coming out through the hole
Press the sock bun scrunchie firmly down your ponytail to your head, fan out your ponytail so that it covers the entire sock and begin folding the hair in your ponytail over the sock scrunchie
Carefully tuck in any stray hairs that have not been folded in while rolling your ponytail into the bun
Secure with bobby pins around the entire bun
